PIC24FJ256DA210 FAMILY
4.1.1
The
word-addressable blocks. Although it is treated as
24 bits wide, it is more appropriate to think of each
address of the program memory as a lower and upper
word, with the upper byte of the upper word being
unimplemented. The lower word always has an even
address, while the upper word has an odd address
(Figure 4-2).
Program memory addresses are always word-aligned
on the lower word and addresses are incremented or
decremented by two during code execution. This
arrangement also provides compatibility with data
memory space addressing and makes it possible to
access data in the program memory space.
4.1.2
All PIC24F devices reserve the addresses between
0x00000 and 0x000200 for hard coded program execu-
tion vectors. A hardware Reset vector is provided to
redirect code execution from the default value of the
PC on device Reset to the actual start of code. A GOTO
instruction is programmed by the user at 0x000000 with
the actual address for the start of code at 0x000002.
PIC24F devices also have two interrupt vector tables,
located from 0x000004 to 0x0000FF and 0x000100 to
0x0001FF. These vector tables allow each of the many
device interrupt sources to be handled by separate
ISRs. A more detailed discussion of the interrupt vector
tables is provided in Section 7.1 “Interrupt Vector
Table”.

4.1.3
In PIC24FJ256DA210 family devices, the top four
words of on-chip program memory are reserved for
configuration information. On device Reset, the config-
uration information is copied into the appropriate
Configuration register. The addresses of the Flash
Configuration
PIC24FJ256DA210 family are shown in Table 4-1.
Their location in the memory map is shown with the
other memory vectors in Figure 4-1.
The Configuration Words in program memory are a
compact format. The actual Configuration bits are
mapped in several different registers in the configuration
memory space. Their order in the Flash Configuration
Words does not reflect a corresponding arrangement in
the configuration space. Additional details on the device
Configuration Words are provided in Section 27.1
“Configuration Bits”.
